Adelie penguin occupancy survey of the Rauer Group, 2009

Occupancy surveys in November 2008 (Southwell and Emmerson 2013) found a total of 13 Adelie penguin breeding sites in the Rauer Group. The boundaries of breeding sub-colonies at 12 of these sites were subsequently mapped from vertical aerial photographs taken for abundance surveys on 21-23 November 2009 (for details of aerial photography see Southwell et al. 2013). The boundaries were mapped with a buffer distance of approximately 1-3 m from the perimeter of penguin sub-colonies.
